Old Dominion pulled off the biggest upset of the season so far, as the 29-point underdogs shocked No. 13 Virginia Tech 49-35. It was the biggest upset by an FBS team over an ACC opponent in the past 40 seasons. C-USA had lost 52 straight games against ranked nonconference opponents. It was also another blow to an already-struggling ACC, as Boston College also lost to Purdue and is likely to fall out of the top 25. Clemson remains the league's lone playoff contender but would benefit most if Miami stays ranked and wins the Coastal. Assuming Clemson wins the Atlantic, it might not face a ranked opponent until the ACC title game. It's SOS will be questioned by the committee, which means little to no margin for error.
